Can motor and tranny mounts look fine but be worthless

Hello,

When I bought my 93 XJ, the driver side motor mount was completely obliterated and the motor had severe issues with moving around with applied throttle. I bought both mounts from auto zone but only replaced the drivers side one, as the passenger one looks pristine. Replacing the mount has made a big difference, but there is still quite a bit of residual vibration that goes through the hole body and exhaust. The passenger mount and tranny mount seem perfectly fine. Is it possible they simply look like that but are worn out, in your experience?

Thanks!

If you replace one, replace them all. Being a new rig to you. They all have the same amount and type of miles on them, as far as you know. I bet with all new mounts you'll little or no more body vibrations. Check out the rubber pieces on your exhaust mounts, too. Just one of those being bad anywhere along the exhaust systerm will cause crazy amounts of vibe noise.
